Abstract
The utility model relates to a self-suction type funnel cap for a household flue, which is mainly composed of a base vertically fixed at an outlet of a smoke (gas) flue, an upper and a lower groups of fan blades (three-blade type or two-blade type), turbine blades, a center shaft, circular rings, a top cover and bearings, wherein the root parts of the upper and the lower groups of fan blades which are connected in series are connected with a vertical centre shaft up and down via the upper and the lower two bearings, blade tips of the fan blades are respectively connected with both ends of each turbine blade via the upper and the lower two circular rings, so that the whole blades can freely rotate around the centre shaft under the action of natural wind in any direction or under the action of rising smoke (gas) flow in the smoke (gas) flue; the turbine blades are a plurality of cambered and bar-shaped sheets, both ends of each turbine blade are connected with the blade tips of the fan blades respectively via the upper and the lower two circular rings, and a proper installation angle is favorable to the integral appearance shape of the funnel cap. The utility model has better aerodynamic performance, has the advantages of good balance performance and stability, has aiding and discharging action which is greater than that of four-blade type fan blades, and is not easy to vibrate. The utility model is suitable for a vertical outlet at a roof of a smoke (gas) discharging flue of a kitchen in a house and a vertical outlet at a roof of a smoke (gas) discharging flue a toilet in a house.
Description
Technical field
The utility model relates to a kind of dwelling house cigarette (gas) road blast cap, particularly relates to the roof vertical outlet blast cap in house kitchen and toilet smoke evacuation (gas) road.
Background technology
Serious day by day along with environmental problem, except the atmosphere pollution that industrial production and vehicular discharge cause, the agenda of environmental improvement has been listed in the intensive domestic pollution that brings of urban population in.For example house kitchen, toilet smoke evacuation, the improper secondary pollution that causes of exhaust have obtained the attention of national departments concerned.Nation-building portion and each province construction department put into effect the pertinent regulations of house kitchen, toilet smoke evacuation, exhaust in succession, promptly can not directly arrange to entering atmosphere from the roof through flue outside window.Usually, the outlet of cigarette (gas) road is exposed to the roof, has wind weather to form and pours in down a chimney; Rain, snow and other thing can fall in cigarette (gas) road, not only influence smoke evacuation (gas) effect, and may cause other problem.At the exit opening in cigarette (gas) road blast cap is installed and is overcome above-mentioned unfavorable problem, can also when wind weather is arranged, form the self-priming effect and strengthen smoke evacuation (gas) effect, and when calm weather, not hinder smoke evacuation (gas).This type of used both at home and abroad blast cap or can not self-priming when wind weather is arranged, or hinder smoke evacuation (gas) during calm weather is (as utility model patent: pneumatic type blast cap, the patent No.: ZL01250220.0)
There is following defective in existing cigarette (gas) road blast cap:
1. hinder smoke evacuation (gas) during calm weather, promptly its top cover has stoped the outflow of cigarette (gas), has hindered the smooth discharge of cigarette (gas).
2. when wind weather was arranged, still there was outflow (discharge) problem that stops cigarette (gas) in its top cover.
3. cross flabellum easily vibrates, and stability is poor.
4. when flabellum weight is identical, a little less than smoke evacuation (gas) ability of cross flabellum (four leaves) than three leaves (or two leaves) type flabellum
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of and have the snow that protects from the wind and rain, stop other thing to fall into to form self-priming in cigarette (gas) road, when wind weather is arranged and do in order to strengthen smoke evacuation (gas) function, when calm weather, do not hinder smoke evacuation (gas) and the good house kitchen of stability, the self-priming blast cap in exit opening place in toilet cigarette (gas) road.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
The utility model mainly is made up of flabellum (three leaves or two blade profiles), turbo blade, top cover, axis, annulus and the bearing of the base that is vertically fixed on the outlet of cigarette (gas) road, upper and lower two groups of polyphones.The root of the flabellum (three leaves or two blade profiles) of upper and lower two groups of polyphones passes through up and down, and two bearings link to each other up and down with axis; Its blade tip passes through up and down, and two annulus link to each other with the two ends of serial turbo blade respectively, then this integral body can natural wind effect in any direction under, or the cigarette that rises in cigarette (gas) road (rotates freely around axis under the stream effect, does in order to strengthen the effect of smoke evacuation (gas) thereby form self-priming.Turbo blade is several arc strip thin slices, its two ends are passed through up and down respectively, and two annulus link to each other with the flabellum blade tip, suitable setting angle helps the monnolithic case moulding of blast cap and has better aerodynamic performance, enough spaces had both helped discharging cigarette (gas) between each turbo blade, helped shading wind and rain snow again.Top cover is that two recessed circular curved surfaces fastenings of epirelief form, and its center is passed axis and is vertically connected with axis, and disconnects with turbo blade and connected components thereof, and forms enough spaces between the outlet of top flabellum.Upper convex surface helps sleet and flows away, and following concave curved surface helps flabellum exit, top and forms low pressure to strengthen the flue pumping performance.The vertical range of top cover and the outlet of upper fan sheet is in 0.2-1.5 times of circle diameter scope.
The utlity model has following advantage:
1, compares with four blade profile flabellums, when keeping the flabellum gross area constant, because of can increasing suction force, the increase of each sheet area of three leaves (or two leaves) type flabellum more helps cigarette (gas) road smoke evacuation (gas), the row of helping that the formation self-priming helps row to act on than single-stage four blade profile flabellums thereby the drive turbo blade rotation of the wind comes from naturally of any direction drives the two-stage flabellum rotation of upper and lower polyphone acts on greatly, during calm weather in cigarette (gas) road the rising cigarette (have the self-priming effect under the effect of stream equally, still help to discharge cigarette (gas).
2, the top cover that links to each other with axis disconnects with turbo blade and connected components thereof, and and the outlet of top flabellum between the enough spaces of formation, when calm weather, do not hinder exhaust; The function that has shading wind and rain snow equally.
3, the trilobal cross flabellum is good than four blade profile flabellum balance qualities, and is stable, is difficult for vibration.
